Noise&Vibration Dosimeter

The instrument significantly decreases the measurement uncertainty related to the estimation of daily exposure time as it is small enough to take dailyvibration exposure measurements without interfering withnormal working activities.
Noise Dosimeter is been designed for the accurate measurement of noise exposure to ISO 9612 and MIRE (microphone in real ear) measurements to ISO 11904-1. 1/1 and 1/3 octave analysis options are available.
